Abstract
A radio base station apparatus of the invention includes a scramble code-generating part that generates a different scramble code for each sector, at least for adjacent sectors, and a scrambling part that uses a scramble code generated by said scramble code-generating part to scramble a scrambling-target portion in said downlink sub-frame. This contributes to increasing extraction precision when extracting a desired signal from a signal that was affected by interference between/among sectors.
